    摘要： Disclosed is a waveguide adapter able to generate a circularly polarized wave. The waveguide adapter to be coupled with a horn antenna realizes a polarized wave conversion function for converting a linearly polarized wave signal into a circularly polarized wave signal, or vice versa, and an adapter function for converting a waveguide signal into an external transmission line signal, resulting in a simplified configuration and small size of a communication system using a circularly polarized wave signal. The waveguide adaptor includes a probe to transmit a linearly polarized wave signal from an external transmission line to a waveguide transmission line, a polarized wave conversion line reflector located in the rear of the probe to convert a vertically polarized wave into a horizontally polarized wave, and a back-short member to forwardly transmit a rearward signal. The waveguide adapter is applicable to communication systems using circularly polarized wave signals.

    摘要： An antenna comprises a polarizer, a phasing network and a field radiating element such as a horn. The polarizer and phasing network generate a plurality of phase shifted circularly polarised waves which are superimposed to produce multiple antenna field patterns from a single antenna aperture.

    摘要： A polarizer for a dual frequency band is formed of square waveguides of a dual structure. A section is formed which extends in a step-like manner as deeper inside between outer and inner square waveguides. The section is connected to the inner square waveguide at an output portion. A third section protrudes from the sidewall of the inner square waveguide, which section extends in a step-like manner as deeper inside and connected to the other sidewall of the square waveguide at the output portion to provide two divided rectangular waveguides.

    摘要： A device is disclosed for converting a circularly polarized electromagnetic radiation into linearly polarized electromagnetic radiation. The device includes a depolarizer with depolarizing elements supported in a polarization mode converter for rotation between a vertical output and a horizontal output. A depolarization position for circularly polarized radiation exists between the horizontal output and the vertical output. The rotation direction of the depolarizer can be adjusted to selectively direct left-handed circularly polarized and right-handed circularly polarized radiation either to the vertical or the horizontal output.

    摘要： A device for the filtering of electromagnetic waves propagating in a main rotational symmetrical waveguide element comprising at least one filtering section constituted of a rectangular waveguide section inserted in being spliced into the main waveguide element, each transition between said main waveguide element and each of said filtering sections being made by metal walls which are substantially perpendicular to said axis of symmetry, the number and the geometrical and dimensional characteristics of the filtering sections being chosen so as to constitute a filter with a pre-determined filtering profile. The device can be applied especially in dual band filtering, for example for the making of dual band or bi-polarization duplexers.
